TracoPower DC/DC Converters, TSR 3 Series

TracoPower Brand: TracoPower

A range of TracoPower 3A DC/DC Converters from the TSR-3 Series. These TSR 3 models are non isolated step down switching regulators that can also be operated with a negative output voltage.

The converters are supplied in a very compact open frame package of 15.5 x 9.4 x 6.2mm. The high efficiency of up to 95% admits a full load operation up to 50°C and up to 85°C with 50% current reduction. They have a low standby current and a wide input range. As the converters do not need a heatsink, this gives them a significant advantage over linear regulators.
Together with a remote On/Off input and protection against short circuit and over temperature these converters are ideal load regulators for high reliable and energy critical applications.
